I've (unfortunately) been refilling so infrequently these days that I don't mind the few extra seconds it takes me to unpeel my aluminum tape, refill, and fold it back on. I'm not at all convinced it is required, but again, I refill so infrequently that I figure it doesn't hurt.
I 100% agree with others regarding aluminum tape. Once I started using it to plug holes, I've never had a second thought of going back to plugs, hot glue, other tape, screws, etc. When I put it on, I fold a tiny bit of it back onto itself so it gives me a little loose edge to grip onto when removing. Again, I don't 100% remove, I just peel it out of the way enough to get my needle in.
